<P><BIG>
File <NOBR>83C51F.MCU</NOBR> has been renamed to 83C51FX.MCU and completed
with the &quot;mysterious IPH register&quot; and related commentary.<BR>
The SFR symbol definitions in file <NOBR>83C750.MCU</NOBR> have been changed
according to manufacturer specifications.<BR>
The BIT symbols for P1.0 thru P1.3 in file <NOBR>83C515A.MCU</NOBR> have been
changed according to their equivalents in the new file <NOBR>C515C.MCU</NOBR>.<BR>
File <NOBR>C517A.MCU</NOBR> replaces <NOBR>83C517A.MCU</NOBR>, because the
C517A is functionally identical (with some slight differences in naming
conventions only).<BR>
Note that all <STRONG>SIEMENS</STRONG> derivatives are now manufactured
and sold by <STRONG>Infineon</STRONG>!

<STRONG>Credits:</STRONG><BR>
Axel Kielhorn has written the file <NOBR>DS5000.MCU</NOBR>.<BR>
Anders Sandstr&ouml;m has sent me <NOBR>87LPC762.MCU</NOBR> and
<NOBR>87LPC768.MCU</NOBR>.
